Range limited
Works well but 6m is optimistic in my room with furniture. Closer range is very reliable though.

Good but config needed
Detection is accurate once tuned. The Bluetooth app took some time to connect initially but works well now.

Great for home automation
Works perfectly with my smart lights. The ability to detect static presence is a game changer compared to PIR sensors.
